FIELD OF THE INVENTION

The present invention relates to novel substituted 2-amino-fused heterocyclic compounds, such as 2-amino-quinolines, 2-amino-isoquinolines, and 2-amino-quinazolines, compounds of formula (I), to pharmaceutical compositions comprising the compounds, as well as to the use of the compounds in the preparation of a medicament for use in the treatment or prevention of a disease or medical condition mediated through c-Jun N-terminal kinases (JNKs), leading to a decreased glucose threshold for insulin secretion. In addition the compounds are predicted to lower blood glucose by increasing hepatic glucose uptake. Such compounds may have utility in the treatment of Type 2 diabetes and obesity.

BACKGROUND OF THE INVENTION

Mammalian cells respond to extracellular stimuli by activating signaling cascades that are mediated by members of the mitogen-activated protein (MAP) kinase family, which include the c-Jun N-terminal kinases (JNKs), also known as stress activated protein kinase (SAPK). Three distinct genes, JNK1, JNK2, JNK3 have been identified and at least ten different splicing isoforms of JNKs exist in mammalian cells [Gupta et al., EMBO J., 15:2760-70 (1996)]. While JNK1 and JNK2 express in many tissues, JNK3 specifically expresses in the brain. Thus, JNK3 has a potential to be particularly involved in nervous function. The JNK signal transduction system of stress response MAP kinase family system is activated by changes in osmotic pressure, DNA damage, anisomycine, heat shock, ultraviolet radiation, ischemia, inflammatory cytokines and the like and various stress stimulations relating to apoptosis induction, it is considered to constitute a major intracellular information transduction path responsible for stress response (Biochemica et Biophysica Acta, vol. 1333, pp. F85-F104 (1997)). From an experiment using a JNK1 deletion mouse, JNK is reported to be an important mediator involved in obesity and insulin resistance (Nature, vol. 420, pp. 333-336 (2002)).

N-3 is treated with potassium hydroxide to afford the phenol N-4, which is in turn globally methylated under standard conditions (such as methyl iodide in the presence of a suitable base) to yield the ether-ester N-5. Reduction of the nitro group under standard hydrogenation conditions to N-6 followed by cyclisation with urea yields the quinazoline N-7. Dichlorination to N-8, mono chloro-removal to N-9 and 2-chloro displacement to N-10 was performed as described in scheme A.

The mixture was heated to 70° C. for 1 hr. The solution appeared dark. After the reaction finished, the MeOH solvent was removed by vacuum and the residue was dissolved in CH₂Cl₂ (100 ml). The organic phase washed with water (3×50 mL), then brine (1×30 mL). The organic layer was dried over magnesium sulfate, and filtered and the solvent reduced under vacuum. The product was purified by a silica gel column with 100% EA to give about 40.0% of desired product of 2,2-diethoxyacetamidine (O-2). The 2,2-diethoxyacetamidine (O-2) was dissolved in 6 ml of concentrated H₂SO₄ (99.9%) and the reaction was stirred at 40° C. for 72 hours. The solution was neutralized by 1M NaOH aqueous to PH 7.0. The crude was purified by silica gel column with 50:50 (petroleum ether: EA) to give final product O-1; yield from 13% to 70% depending on the substitution of phenyl methane amidine.

Shown in scheme P is the synthesis of intermediates compounds P-1 containing N-1,4-dioxaspiro[4.5]dec-8-yl-isoquinolin-3-amine. In the glove box, isoquinolin-3-amine (O-1) (873 mg, 3.7 mmol) was dissolved in 10 ml THF in flask and NaH (133.0 mg, 5.5 mmol) was added. The mixture was stirred at ambient temperature for 20 min. to form the N-sodium salt solution, followed by addition of Ti(OPr)₄ (4.2 g, 14.8 mmol) and 1,4 cyclohexanedione ethylene ketal (1.2 g, 7.2 mmol). Capped the flask and placed in an oil bath at 50° C. for 16 hours with stirring. The NaBH₄ was added and stirred at 50° C. for 16 hours. The solvent was removed by vacuum and the residue was dissolved in CH₂Cl₂ (100 ml). The organic phase washed with water (3×50 mL), and then brine (1×30 mL). The organic layer was dried over magnesium sulfate, and filtered and the solvent evaporated under vacuum. The crude material was purified by a silica gel column with 50:50 (EA/Petroleum) to give final products (P-1) with yield from 35% to 51% depending the substitutions on the isoquinoline.

Shown in scheme Q is the synthesis of intermediates compounds Q-1 containing 4-(isoquinolin-3-ylamino)cyclohexanone. The (1,4-Dioxa-spiro[4.5]dec-8-yl)-(8-fluoro-6-methyl-isoquinolin-3-yl)-amine (P-1) (510.0 mg, 1.4 mmol) was dissolved in a solution of 20 ml of THF and 15 ml of 1 M HCl. The reaction was heated in 50° C. for 1 hour. LC/MS showed no more start material remained. The solution was neutralized by sodium carbonate (1 M Na₂CO₃ aqueous to neutralized the solution to pH=8), The THF was evaporated and partitioned with CH₂Cl₂/water. The organic layer was evaporated to give the product (Q-1) for next step without further purification.

Shown in scheme R is the synthesis of intermediates compounds R-1 and R-2 containing cis and trans-4-(isoquinolin-3-ylamino)cyclohexanol. The 4-(Isoquinolin-3-ylamino)-cyclohexanones (Q-1) and NaBH₄ was dissolved in MeOH with stirring for 2 hrs at 50° C. LC/MS showed no more start material left and cis and trans products in about 1:1 ratio. The solvent was evaporated and partitioned with EA/water. The organic layers were evaporated. The cis (R-1) and trans (R-2) products were separated by HPLC with a combined yield ranging from 70% to 85%.

Shown in scheme S is the synthesis of intermediates compounds S-1 containing 6-(1H-pyrazol-4-yl)isoquinolin-3-alkylamines. In a glove box, treatment of tert-butyl 4-(3-aminoisoquinolin-6-yl)-1H-pyrazole-1-carboxylate with 1.5 eq. of NaH in THF at room temperature presumably formed the amino-sodium salt. This reaction accompanied a visible evolvement of H₂. Let the reaction go for 10 minutes before distributing the solution to four vials containing aldehydes and ketones, respectively. To these four vials 4.0 eq of Ti(OiPr)₄ liquid was added. The vials were capped and placed in a 50° C. heating block in fumehood, and stirred for 14 h. After cooling to room temperature, 3.0 eq of NaBH₄ suspended in THF was added to the above reaction vials, respectively, and stirred for 14 h. 2-methoxylethyl ether appeared to solubilize NaBH₄ better and can also be used for the reduction. Carefully, 2N HCl aqueous solution was added to allow the pH to reach 1 or 2. The mixture was stirred for 1 h, and then the pH was adjusted to 8 by adding 2N aqueous NaOH. Precipitate was removed by passing the mixture through a syringe filter. The filtrate was analyzed using LCMS which showed the yields of the desired products ranging from 40 to 70%.

Any of the above compounds described in schemes A-S can be converted into another analogous compound by standard chemical manipulations. These chemical manipulations are known to those skilled in the art and include a) removal of a protecting group by methods outlined in T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis”, Second Edition, John Wiley and Sons, New York, 1991; b) displacement of a leaving group (halide, mesylate, tosylate, etc) with a primary or secondary amine, thiol or alcohol to form a secondary or tertiary amine, thioether or ether, respectively; c) treatment of phenyl (or substituted phenyl) carbamates with primary of secondary amines to form the corresponding ureas as in Thavonekham, B et. al. Synthesis (1997), 10, p1189; d) reduction of propargyl or homopropargyl alcohols or N-BOC protected primary amines to the corresponding E-allylic or E-homoallylic derivatives by treatment with sodium bis(2-methoxyethoxy)aluminum hydride (Red-Al) as in Denmark, S.

The compounds of the present invention may have asymmetric carbon atoms. Diasteromeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods known to those skilled in the art, for example, by chromatography or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixtures into a diastereomric mixture by reaction with an appropriate optically active compound (e.g., alcohol), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. All such isomers, including diastereomeric mixtures and pure enantiomers are considered as part of the invention.

The compounds of formulas (I) that are basic in nature are capable of forming a wide variety of different salts with various inorganic and organic acids. Although such salts must be pharmaceutically acceptable for administration to animals, it is often desirable in practice to initially isolate the compound of formula (I) from the reaction mixture as a pharmaceutically unacceptable salt and then simply convert the latter back to the free base compound by treatment with an alkaline reagent and subsequently convert the latter free base to a pharmaceutically acceptable acid addition salt. The acid addition salts of the base compounds of this invention are readily prepared by treating the base compound with a substantially equivalent amount of the chosen mineral or organic acid in an aqueous solvent medium or in a suitable organic solvent, such as methanol or ethanol. Upon careful evaporation of the solvent, the desired solid salt is readily obtained. The desired acid salt can also be precipitated from a solution of the free base in an organic solvent by adding to the solution an appropriate mineral or organic acid.

Those compounds of formula (I) that are acidic in nature are capable of forming base salts with various pharmacologically acceptable cations. Examples of such salts include the alkali metal or alkaline-earth metal salts and particularly, the sodium and potassium salts. These salts are all prepared by conventional techniques. The chemical bases which are used as reagents to prepare the pharmaceutically acceptable base salts of this invention are those which form non-toxic base salts with the acidic compounds of formula (I). Such non-toxic base salts include those derived from such pharmacologically acceptable cations as sodium, potassium calcium and magnesium, etc. These salts can easily be prepared by treating the corresponding acidic compounds with an aqueous solution containing the desired pharmacologically acceptable cations, and then evaporating the resulting solution to dryness, preferably under reduced pressure. Alternatively, they may also be prepared by mixing lower alkanolic solutions of the acidic compounds and the desired alkali metal alkoxide together, and then evaporating the resulting solution to dryness in the same manner as before. In either case, stoichiometric quantities of reagents are preferably employed in order to ensure completeness of reaction and maximum yields of the desired final product.

The compounds of the present invention may also be useful in the treatment of other metabolic disorders associated with impaired glucose utilization and insulin resistance include major late-stage complications of NIDDM, such as diabetic angiopathy, atherosclerosis, diabetic nephropathy, diabetic neuropathy, and diabetic ocular complications such as retinopathy, cataract formation and glaucoma, and many other conditions linked to NIDDM, including dyslipidemia glucocorticoid induced insulin resistance, dyslipidemia, polycysitic ovarian syndrome, obesity, hyperglycemia, hyperlipidemia, hypercholesteremia, hypertriglyceridemia, hyperinsulinemia, and hypertension. Brief definitions of these conditions are available in any medical dictionary, for instance, Stedman's Medical Dictionary (Xth Ed.).

Methods of preparing various pharmaceutical compositions with a specific amount of active compound are known, or will be apparent, to those skilled in this art. In addition, those of ordinary skill in the art are familiar with formulation and administration techniques. Such topics would be discussed, e.g. in Goodman and Gilman's The Pharmaceutical Basis of Therapeutics, current edition, Pergamon Press; and Remington's Pharmaceutical Sciences, current edition. Mack Publishing, Co., Easton, Pa. These techniques can be employed in appropriate aspects and embodiments of the methods and compositions described herein. The following examples are provided for illustrative purposes only and are not meant to serve as limitations of the present invention.

The amino heterocyclyl compounds of formula (I) may be provided in suitable topical, oral and parenteral pharmaceutical formulations for use in the treatment of GK mediated diseases. The compounds of the present invention may be administered orally as tablets or capsules, as oily or aqueous suspensions, lozenges, troches, powders, granules, emulsions, syrups or elixirs. The compositions for oral use may include one or more agents for flavoring, sweetening, coloring and preserving in order to produce pharmaceutically elegant and palatable preparations. Tablets may contain pharmaceutically acceptable excipients as an aid in the manufacture of such tablets. As is conventional in the art these tablets may be coated with a pharmaceutically acceptable enteric coating, such as glyceryl monostearate or glyceryl distearate, to delay disintegration and absorption in the gastrointestinal tract to provide a sustained action over a longer period.

Formulations for oral use may be in the form of hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin. They may also be in the form of soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin or olive oil.

Aqueous suspensions normally contain active ingredients in admixture with excipients suitable for the manufacture of an aqueous suspension. Such excipients may be a suspending agent, such as sodium carboxymethyl cellulose, methyl cellulose, hydroxypropylmethyl cellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; a dispersing or wetting agent that may be a naturally occurring phosphatide such as lecithin, a condensation product of ethylene oxide and a long chain fatty acid, for example polyoxyethylene stearate, a condensation product of ethylene oxide and a long chain aliphatic alcohol such as heptadecaethylenoxycetanol, a condensation product of ethylene oxide and a partial ester derived from a fatty acid and hexitol such as polyoxyethylene sorbitol monooleate or a fatty acid hexitol anhydrides such as polyoxyethylene sorbitan monooleate.

The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension. This suspension may be formulated according to know methods using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation may also be formulated as a suspension in a non toxic perenterally-acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringers solution and isotonic sodium chloride solution. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition fatty acids such as oleic acid find use in the preparation of injectables.

The amino heterocyclyl compounds of formula (I) may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient that is solid at about 25 Celcius but liquid at rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and other glycerides.

For topical use preparations, for example, creams, ointments, jellies solutions, or suspensions, containing the compounds of the present invention are employed.

The amino heterocyclyl compounds of formula (I) may also be administered in the form of liposome delivery systems such as small unilamellar vesicles, large unilamellar vesicles and multimellar vesicles. Liposomes can be formed from a variety of phospholipides, such as cholesterol, stearylamine or phosphatidylcholines.

Dosage levels of the compounds of the present invention are of the order of about 0.5 mg/kg body weight to about 100 mg/kg body weight. A preferred dosage rate is between about 30 mg/kg body weight to about 100 mg/kg body weight. It will be understood, however, that the specific dose level for any particular patient will depend upon a number of factors including the activity of the particular compound being administered, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy. To enhance the therapeutic activity of the present compounds they may be administered concomitantly with other orally active antidiabetic compounds such as the sulfonylureas, for example, tolbutamide and the like.

Example 1 2-(4-methoxyphenyl)-N-[6-(1H-pyrazol-4-yl)isoquinolin-3-yl]acetamide

Activation of (4-Methoxy-phenyl)-acetic acid (315.6 mg, 1.9 mmol) is accomplished by treatment of the carboxylic acid in DMA (5 mL) with HATU (802.6 mg, 2.1 mmol) and triethylamine (388.2 mg, 3.8 mmol) at room temperature for 1 hour. The 6-(1H-Pyrazol-4-yl)-isoquinolin-3-ylamine (200.0 mg, 0.9 mmol) was added and the mixture was stirred at 75° C. for 24 hours. The reaction was monitered by LC/MS. Evaporation of DMA gave a residue that was washed with NaHCO₃ to remove the by-products from HATU. The crude residue then was dissolved in MeOH (10 mL) and was treated with K₂CO₃ (26.0 mg, 0.5 mmol) at 75° C. for 18 hrs. The solvent was evaporated and the product extracted with CH₂Cl₂ (20 mL). The extracts were washed with water (3×10 mL) and evaporated. The crude product was purified by ISCO (with petroleum ether:ethyl acetate 50:50) to give the title compound as a light yellow crystalline solid product (143.3 mg, 41.4%). ¹H NMR (DMSO-d₆, 400 MHz): δ 3.68 (2H, s), 3.73 (3H, s), 6.79-6.98 (2H, m), 7.31 (2H, d, J=8.8 Hz), 7.81 (1H, dd, J=8.6, 1.5 Hz), 8.00 (1H, d, J=8.6 Hz), 8.08 (1H, s), 8.14 (1H, s), 8.41 (2H, d, J=8.3 Hz), 9.03 (1H, s), 10.69 (1H, s), 13.09 (1H, s). ¹³CNMR (DMSO-d₆, 100 MHz): δ 42.18, 55.01, 106.30, 113.76, 120.44, 120.56, 124.11, 124.39, 126.71, 127.87, 128.06, 130.13, 135.26, 136.96, 137.87, 147.51, 150.75, 158.14, 170.14.

Preparation of Intermediate 1: N-(4-Bromobenzyl)-2,2-diethoxyethanimidamide

In a 2 L, three-neck round bottom flask (equipped with magnetic stir bar, thermometer, and addition funnel), charged diethoxyacetonitrile (111.1 g, 860 mmol) and methanol (620 mL, anhydrous) while under a steady nitrogen flow. Via an addition funnel, slowly charged 25 wt % solution of sodium methoxide (4.64 g, 86 mmol, 19.7 mL) in methanol. (Note: addition is slightly exothermic). The mixture was stirred for 15 h, at which point, the solvent was removed under vacuum (Note: starting material had not been completely converted according to NMR). The residue was dissolved in methanol and charged with a fresh sodium methoxide solution—same concentration/equivalents—and stirred another 15 h). The solvent was removed under vacuum and the residue was dissolved in diethyl ether (1.0 L), with the organic phase washed with water (3×500 mL), then brine (1×300 mL). The organic layer was dried over magnesium sulfate, the salts filtered and the solvent reduced under vacuum to give 89.9 g of a crude mixture of methyl 2,2-diethoxyethanimidoate and un-reacted starting material (10-12 mol % by NMR) as a thin oil. Note that best yields of the imidate are obtained when the organic layer is stripped of at 400 mbar and 45° C. because of its volatility.

The oil was dissolved in methanol (300 mL,) and placed into a 2 L round bottom flask (equipped with magnetic stir bar, reflux condenser) along with 1-(4-bromophenyl)methanamine (100.0 g, 537 mmol) and the mixture subjected to heating in a pre-heated oil bath. The mixture was stirred at 70° C. for 18 h and then allowed to cool. The solvent was removed to give 158.8 g of the desired intermediate (1) in 93.8% yield (based on 1-(4-bromophenyl)methanamine as limiting reagent).

Preparation of Intermediate 2: 6-Bromoisoquinolin-3-amine

In a 3 L, three-neck round bottom flask (equipped with magnetic stir bar, thermometer, addition funnel), charged conc. sulfuric acid (1.12 L). While maintaining an internal temperature of 20-25° C. with an ice water bath, dropwise charged N-(4-bromobenzyl)-2,2-diethoxyethanimidamide (158.8 g, 504 mmol). After addition, removed bath and allowed to stir at ambient temperature for 72 h.

A 12-L, 3-necked round bottom flask, equipped with a large stirrer bar, dropping funnel and thermometer was charged with water (5 L). The flask was placed in an IPA bath and cooled externally with solid CO₂ to an internal temperature of 8° C. Over a period of 1¾ h, the reaction mixture was added slowly to the water, keeping the internal temperature between 0° C. and 10° C., resulting in a yellow suspension. With continued cooling, a 12 M NaOH solution was added over a 4 h period, keeping the internal temperature below 30° C. A final pH of 9-10 was reached (required 4.6 L, 12 M NaOH). Note that upon reaching neutral pH, the suspension changed to a much darker yellow. The suspension was filtered over a medium glass filter and the remaining residue was washed repeatedly with a total of 4 L of water to wash away precipitated Na-salts which resulted in a significant decrease of the amount of solids on the filter. The residue was dried in high vac at room temperature over KOH to give 143 g of a yellow powder. Elemental analysis showed 5.9 weight % of Na which corresponds to 36.4 weight % of Na₂SO₄. This material was used for further elaboration.

Preparation of Intermediate 3: 6-(1H-Pyrazol-4-yl)isoquinolin-3-amine

A 3-L, three-necked rbf, equipped with a condenser, thermometer and large stirrer bar was charged with DME (1 L) and a 2M Cs₂CO₃ (1 L, 10 eq). The two-phased system purged with nitrogen under vigorous stirring for 45 min, followed by the addition of 6-bromoisoquinolin-3-amine (44 g, 64 w % purity, 126 mmol), the commercially available boronate (50 g, 170 mmol), and PdCl₂(dppf), CH₂Cl₂ complex (10.6 g, 14.2 mmol, Strem) and MeOH (2 mL). The nitrogen purge was discontinued and replaced by a nitrogen in/outlet on top of the condenser. The reaction mixture was heated to rfx (internal temperature 80° C.) for a period of 16 h and allowed to cool to room temperature. The cooled reaction mixture appeared as a two-layer system with a virtually colorless, aqueous layer and a dark organic layer in which a light brown precipitate had formed. The reaction mixture was filtered over a short path of Celite (pre-wetted with MeOH) and the Celite was subsequently washed with DME (110 mL). Removal of the solids improved visibility and the water layer could be readily separated. The organic layer was further diluted with ethyl acetate (700 mL) resulting in the separation of more solids which were remove by short-path filtration over a fresh batch of Celite (pre-wetted with MeOH). The filtrate was concentrated to a volume of 30 mL and the formed solids were isolated by filtration and washed with diethyl ether (40 mL) to give 4.8 g (11%) of the desired product as a yellow solid.

An alternative procedure for the preparation is as follows: To a 3-necked flask equipped with stirrer, nitrogen inlet and internal thermometer was charged with 3-amino, 6-bromoisoquinoline (6.0 g, 20.0 mmol), 2-(2′,6′-dimethoxybiphenyl)dicyclohexylphosphine (S-Phos) (2.0 g, 3.0 mmol), thoroughly freshly degassed DME (200 mL), water (40 mL), and Cs₂CO₃ (46.2 g, 142.0 mmol). The suspension was placed under nitrogen in a pre-heated oil bath at 86° C. Meanwhile, a solution of 1-BOC-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazole (10.8 g, 36.0 mmol) in degassed DME (30 mL) was prepared and stored under nitrogen. When the internal temperature of the suspension had reached 84° C., the Pd₂(dba)₃ (2.8 g, 3.0 mmol) was added, and quickly followed by dropwise addition of the pyrazole boronate solution (via syringe over 5 min). The resulting bi-phasic dark orange solution was stirred at 84° C. for 20 mins. The flask was then placed in an ice bath to cool rapidly. Once at ambient temperature, the mixture was filtered to remove inorganic substance, washed with water (2×25 mL). Upon reduction of the solution volume via evaporation the solid product was filtered and collected. The light yellow product was washed with ethyl ether 3 time (20 ml) to give a pale yellow solid product. Yield: 6.1 g, 98.4%.

Example 2 2-(5-methoxy-2-methyl-1H-indol-3-yl)-N-[6-(1H-pyrazol-4-yl)isoquinolin-3-yl]acetamide

To a solution of 2-(5-methoxy-2-methyl-1H-indol-3-yl)acetic acid (219.2 mg, 0.5 mmol) in 5 mL of anhydrous THF was added oxalyl chloride (119.6 mg, 0.95 mmol), and 100 μL of DMF also was added. A effervescence occurred. Within 1-4 minutes the effervescence stopped. The mixture was stirred for 30 minute at room temperature, followed by addition of 6-(1H-Pyrazol-4-yl)-isoquinolin-3-ylamine in 5 mL of pyridine (100.0 mg, 0.5 mmol). The reaction was stirred at the ambient temperature over 16 hours as it was monitored by LC/MS. To the reaction mixture was added K₂CO₃ (196.7 mg, 1.4 mmol) and water (2 mL). The solution was heated to 70° C. for 5 hours. Removal of the solvents provided a crude mixture that was purified by HPLC using H₂O/CH₃CN/0.1% acetic acid as a mobile phase to give the title compound as a crystalline solid product (9.9 mg, 5.1%). ¹H NMR (DMSO-d₆, 400 MHz): δ 3.68 (2H, s), 3.73 (3H, s), 6.90 (2H, d, J=8.8 Hz), 7.31 (2H, d, J=8.6 Hz), 7.31 (1H, d, J=8.6 Hz), 7.81 (1H, dd, J=8.6, 1.5 Hz), 8.00 (1H, d, J=8.8 Hz), 8.08 (1H s), 8.10-8.22 (1H, m), 8.40 (2H, s), 9.03 (1H, s), 10.69 (1H, s), 13.09 (1H, s). ¹³CNMR (DMSO-d₆, 100 MHz): δ 40.13, 55.00, 106.29, 113.75, 120.55, 124.10, 124.38, 127.87, 128.04, 130.12, 135.25, 137.87, 147.50, 150.75, 158.04, 170.13.

The reaction mixture was heated to 86° C. for 7 h. After cooled to room temperature, acetic acid was removed in vacuo. The residue was dilute by 200 mL of water, followed by addition of concentrated HCl to PH˜1. The water layer was extracted by EtOAc (300 mL×3), the combined organic layers were dried (Na₂SO₄) and concentrated in vacuo. The solid was washed by Hexanes/DCM (200 mL/5 mL) to afford 4,5-dimethoxyindane-1-carboxamide (9.1 g, 36.4%). The filtrate was concentrated in vacuo and then purified by chromatography (MeOH/DCM: 1/99) to afford 4,5-dimethoxyindane-1-carboxylic acid as off-white solid (2.7 g, 11%).

The mixture of 4,5-dimethoxyindane-1-carboxamide (8.4 g, 38.0 mmol), KOH (6.4 g, 114.0 mmol), MeOH (31.0 mL) and water (62 mL) was heated to refluxed for 14 h. The reaction mixture was cooled to room temperature, and MeOH was removed in vacuo. The residue was diluted by 50 mL of water, and the aqueous mixture was extracted with EtOAc (50×2). The aqueous layer was added conc. HCl to adjusted pH ˜1. The solid was filtered, washed by water (100 mL), and dried over P₂O₅ to afford 4,5-dimethoxyindane-1-carboxylic acid as off-white solid (7.7 g, 92%). M. P.: 128˜130° C.

Biological activity

The percentage of inhibition (at 1 μM or 10 μM unless otherwise stated) and/or the Ki (in nM unless otherwise stated) for the compounds exemplified in the present application were obtained according to the protocol below:

% Inhibition and K_(i) Determination

A coupled spectrophotometric assay, coupling JNK1α1 activity to the oxidation of β-NADH to NAD+ through the action of pyruvate kinase (PK) and lactic dehydrogenase (LDH), was used to determine the potency (percent inhibition at 1 or 10 μM or K_(i)) of compounds against JNK1α1 (Genbank Accession Number: L26318). The final reaction conditions were as follows: 20 mM HEPES pH 7.6, 10 mM MgCl₂, 1 mM DTT, 200 μM peptide substrate (KRELVEPLTPSGEAPNQALLR), 300 μM NADH, 500 μM PEP (phophoenolpyruvate), 9-10 units/mL LDH, 8-12 units/mL PK, 40 nM JNK1α1_(—)364nHis (catalytic domain containing amino acids 1-364 and N-terminal hexahistidine tag, previously activated by MKK4 and MKK7beta in vitro), 0-100 μM test compound, 2.5% DMSO, and 50 μM ATP (2.5× Km). The reaction was monitored by following the decrease in absorbance at 340 nm. The initial reaction rate was determined by the slope of the change in absorbance. To calculate percent inhibition the rate of the reaction in the presence of 1 or 10 μM compound was compared to the rate of the reaction with only DMSO multiplied by 100 percent. Note, the background rate of the above reaction in the presence of 10 μM PHA-00738186 was subtracted from all rates. To calculate the K_(i), the reaction rates (with the background subtracted) were plotted vs. the compound concentration (0-100 μM) and fit to the tight binding for competitive inhibitors (Morrison) equation (see below).

Formula

Y=(−X+Eo−(Ki*(1+A/Km))+((X−Eo+(Ki*(1+A/Km)))̂2+4*Eo*(Ki*(1+A/Km)))̂0.5)*(Vm*A/(Km+A)/(2*Eo))

-   -   Parameters: Eo, Ki, A, Km, Vo     -   Y is initial reaction velocity;     -   X is inhibitor concentration;     -   A is [ATP];     -   Ki is inhibition constant;     -   Vm is Vmax;     -   Eo is total (initial) enzyme concentration;     -   Km is ATP Km;

The compounds were prepared in 100% DMSO at a 40× concentration. For percent inhibition experiments this would be 400 or 40 μM for 10 and 1 μM final concentration, respectively. For the Ki determination 3× serial dilutions were made starting at 4 mM (100 μM at 1×) in DMSO. A total of 11 concentrations were used for the analysis. The compounds were added to the reaction plate first. Next, a solution containing the HEPES, MgCl₂, DTT, peptide substrate, NADH, PEP, PK/LDH enzyme, and JNK1α1_(—)364nHis enzyme was added to the assay plate. The plate was incubated at room temperature for 15 minutes. Then the plate was warmed to 30° C. for 5 minutes. The reaction was initiated with the addition of ATP. The reaction was run in a plate reader at 30° C. for 20 minutes with absorbance readings made about every 10 seconds.

JNK1α1 364nHis Purification Procedure

Growth and Induction Conditions

BL21 (DE3) cells containing JNK1α1_(—)364nHis vector were grown at 37° C. until optical density (OD₆₀₀) was between 0.6 to 0.8. Expression was induced by addition of isopropylthiogalactoside (IPTG) to a final concentration of 0.1-0.2 mM and incubated at 23° C. overnight. The cells were harvested at 5000 rpm for 15 minutes at 4° C. The cell pellet can be stored at −80° C. for future purification.

Purification Procedure

-   -   1. Cell pellet (1 L culture) was resuspended with lysis buffer         at 5-10 mL/wet cell pellet. The maximum and minimum volumes were         350 mL and 60 mL.
